Description
Technical field
The present invention relates to a kind of push button locking device, it is arranged to unclamp (unlatching) locking mechanism by means of the bulldozing operation that is contained in a plurality of predetermined button on the retainer housing.
Background technology
According to tradition, a kind of push button locking apparatus structure has been arranged, it has many being contained on the retainer housing so that the button that can stretch out and withdraw from one surface.In this housing body, provide a plurality of brake barses, when pressurized so that button moves towards the rear portion of retainer housing and is temporarily fixed at that position corresponding to button.In the retainer housing, provide a sliding part, so that along moving with the direction of brake bars direction of motion quadrature.Preset by button unlatching brake bars by means of bulldozing operation, unclamp locking mechanism (the utility model publication number HEI 2-40206 of reference Japan examination that the retainer enclosure interior is provided with, HEI 3-54281, the patent publication No. HEI 3-78467 of Japan's examination, Japanese unexamined patent publication number HEI 9-256695).
In this case, locking mechanism constitutes in this wise, has the sliding part that the deckle board that is used for engaging the projection of the width side of brake bars separately forms so that slidably be provided with one at inner rim, so that in the retainer housing, move along direction with brake bars direction of motion quadrature, so the rotation and the sliding part interlocking of door handle (also may be door handle).Simultaneously, brake bars form the lock part in its side with respect to the diverse location of press direction and unclamp groove so as with sliding part bump bonds and disengaging.
Therefore, when having only the predetermined unlatching brake bars of pushing, the joint between all brake barses and sliding part projection is released so that allow the sliding part motion.This just unclamps locking so that allow door handle to rotate.Yet in other cases, any brake bars is in its engage sides sliding part projection.This just prevents the sliding part motion and prevents that door handle from rotating, thereby lock-out state is provided.
On the other hand, the brake bars and the brake bars that resets that is provided with dividually with them are all by the surperficial backup of a plurality of back-moving springs towards the retainer housing.In the retainer housing return actuator is set so that can similarly move both vertically with sliding part, it has retainer spring so that engage to open and other side of the width of non-unlatching brake bars and these brake barses are remained on push the position.
This return actuator is inserted between a plurality of buttons and brake bars that vertically are arranged in two row.Open and the locking brake bars has separately and is formed on its intramarginal bonding part of relative width direction, so that engage retainer spring.
Simultaneously, in the edge of brake bars that resets, form and be used for the cam member of motion return actuator.In the bottom of return actuator, form the inclined cam surface that abuts cam member.Therefore, when the reset button pressurized, the brake bars that resets moves upward, thereby retainer spring leaves unlatching and non-unlatching brake bars.So all pressurized brake barses return to their non-pushing position.
In this conventional button formula locking device, the button of pushing towards retainer housing rear portion is placed to and directly abuts brake bars so that towards this this same brake bars of housing rear portion pushing.Therefore, the temporary fixed position of brake bars only is set on the position with respect to retainer housing fore-and-aft direction.
Therefore, this conventional button formula locking device only allow certain button to push once to be provided with " once pushing " open number (for example 1,3,5,7......).By means of pushing certain button many number of times be provided with " repeatedly pushing " open number (for example 1,1,3, be impossible 3......).
So,, just need to arrange button as much as possible and brake bars in order to increase the unlatching number combination of this conventional button formula locking device.Therefore, its defective is: must increase the vertical of retainer housing or width size pro rata with improvement safety purposes.
Summary of the invention
Consider above-mentioned situation, target of the present invention is: a kind of push button locking device is provided, and it allows to increase the combination of opening number and increase button and brake bars quantity not quite greatly by the open operation that the many number of times of same button push are repeatedly pushed.
In order to reach above-mentioned target, the present invention takes following measures:
In other words, of the present invention being characterized as: in aforesaid push button locking device, detent mechanism and intermediary agency are set, detent mechanism is used for temporary fixed set positions with brake bars on many positions of retainer housing fore-and-aft direction, and intermediary agency is used for when button push one time, advances successively towards retainer housing rear portion with the temporary fixed position of the corresponding brake bars of button.
According to the present invention, the temporary fixed position of brake bars is arranged on many positions with respect to retainer housing fore-and-aft direction by detent mechanism, and intermediary agency is set so as whenever button push once, in turn advance towards retainer housing rear portion with the temporary fixed position of the corresponding brake bars of button.Therefore, can adopt repeatedly pushing to carry out open operation, so that at first unclamp this lock by pushing the many number of times of same button.
Hereinafter, will a plurality of preferred embodiment of the present invention be described according to appended patent claims.
In other words, in the present invention, have on detent mechanism is concrete brake bars is advanced to the back-moving spring that does not originally push the position, many be formed in the brake bars with respect to along the bonding part on the retainer housing fore-and-aft direction diverse location, and with cause any bonding part pinning so that the retainer spring of temporary fixed brake bars.
The back-moving spring pushing force in this case, make retainer spring break away from the brake bars bonding part, owing to can make brake bars return and originally not push the position by any back-off assembly.Yet,, may bother very much repeatedly pushing the reset operation that unclamps under the number situation if this brake bars reset operation carries out individually.
Therefore propose, the present invention further comprises return actuator, and it has is manyly pinned so that the retainer spring of temporary fixed brake bars by the bonding part, and can be along moving with the direction of brake bars direction of motion quadrature.Be provided with under the situation of return actuator, by means of only along with the direction of brake bars direction of motion quadrature this return actuator that moves, the bonding part disengagement of all retainer springs and brake bars.By means of the propulsive force of back-moving spring, all brake barses can recover arrival pushing position at once.
In addition, by setting reset brake bars and reset button, the brake bars that resets is used for the motion return actuator so that make retainer spring break away from the bonding part of brake bars, and reset button is used for this brake bars of bulldozing operation, as long as the pushing reset button just can adopt the return actuator of being correlated with to carry out reset operation.
Simultaneously, in the present invention, this intermediary agency is configured with particularly to have many bump bondings and pushes arm, and bump bonding is formed on a plurality of diverse locations with respect to retainer housing fore-and-aft direction, has the top and the base portion that is connected with button of being pinned by any bump bonding and push arm.
In this case, make if this arm top always is arranged in the passage area of brake bars and to push the arm top and engage reliably with the bonding part of unlatching brake bars, even if carried out under the reset operation situation by return actuator, the bump bonding of opening brake bars is pinned by this arm top.Therefore, open brake bars and can not turn back to original not pushing position at once.
Therefore propose the present invention and further comprise an indentation member, it is used for swinging and pushes arm so that push brake bars is left at the top of arm when button does not push passage area, and admission passage zone at first when button push, this top.
In this case, when button does not push, push the arm top and swing to outside the passage area of opening brake bars by the indentation member.Therefore, turn back to when originally not pushing the position when opening the reset operation of brake bars by the moving device that resets, this brake bars can turn back to original not pushing position reliably and do not pinned by the arm top at the bump bonding place.Therefore, reset operation can be carried out reliably by return actuator.

Bolt driving axle 9 is elongated tabular and has indoor end on the hub that is assemblied in indoor handle 5.And the outdoor end of driving shaft 9 inserts the coaxial driving pinion that is installed in outdoor handle 7 inboards.Therefore, because handle 5,7 rotates bolt driving axle 9 on any direction in the left and right sides, just can make in the door bolt retraction door 2.
Bolt driving axle 9 inserts the scallop hole (seeing Fig. 8 and 10) of driving pinion 10 and have the gap on rotation direction.When the locking mechanism 13 that will relate to hereinafter is in the lock state, the rotation of restriction pinion 10, thereby outdoor handle 7 can not rotate on opening direction.And when locking mechanism 13 is opened, allow pinion 10 to rotate, thereby outdoor handle 7 can rotate on opening direction.
That present embodiment push button locking device 1 has is many (in this embodiment altogether nine) button 14, they extended and the withdrawal be located among the surface of retainer housing 6, also have many brake barses 15, they and button 14 are arranged accordingly so that move towards retainer housing 6 rear portions when pressing the button.Because button 14 by depress preset opening brake bars 15B, 15C towards the rear portion of retainer housing 6, just can unclamp locking mechanism 13 in retainer housing 6.
Shown in Fig. 1 to 4, locking mechanism 13 in the retainer housing 6 has guide groove 17, base 19, sliding part 20, brake bars supporting base 21 and bonnet 23, the return actuator 16 (retainer housing 6 vertically) that described guide groove 17 is used for vertically is elongated, base 19 has the brake bars patchhole 18 of many contiguous guide grooves 17 and equidistant vertical arrangement, sliding part 20 is stacked in the outside (upside of Fig. 1) of base 19 slidably, supporting base 21 is stacked on the sliding part 20 in its outside, and the removably closed opening 22 that is formed on the back side of base 19 of bonnet 23.
Brake bars 15 inserts respectively among the brake bars patchhole 18 of base 19 so that move along fore-and-aft direction (along the indoor and outdoor direction).Brake bars 15 also inserts among brake bars patchhole 24 (see figure 5)s that are arranged in the brake bars supporting base 21 respectively.
As shown in Figure 8, sliding part 20 is plate framework members, and it has the size range of surrounding all brake bars patchholes 18 (thereby around all brake barses 15), and is arranged in movingly among the base 19 on its vertical (vertical direction among Fig. 8).Sliding part 20 left side and right-hand member at an upper portion thereof forms respectively and compresses the projection that spring 25 cooperates.Because the top of compression spring 25 abuts the upper head plate 19A of base 19, sliding part 20 is pushing downwards always.
In addition, the sliding part 20 of frame shape can be the discontinuous shape of part excision.Sliding part 20 is forming continuously recessed 26 and projection 27 on sliding part 20 glide directions on its framework inward flange, so that engages with each brake bars 15 on an edge of its width and break away from, place restrictions on whereby and allow sliding part 20 to move.
Because brake bars 15 and button 14 corresponding these embodiment that are provided with prepare four kinds altogether, that is: allow sliding part 20 at the non-unlatching brake bars 15A (Fig. 6 (a) and 6 (b)) of non-pushing state motion, only push and once just allow first of sliding part 20 motions to open brake bars 15B (Fig. 6 (c) and 6 (d)), only push and just allow second unlatching brake bars 15C (Fig. 6 (e) and 6 (f)) that sliding part 20 moves and the brake bars 15D (Fig. 8) that resets that is used for driving return actuator 16 for twice.
In addition, brake bars 15A to 15D and corresponding button 14 are arranged on the ordinate in retainer housing 6 central areas together.Reset brake bars 15D and corresponding reset button 14D (be used for pushing reset brake bars 15D button 14) is arranged in the bottom.Simultaneously, as shown in Figure 6, stretch out pilot pin 28, so that prevent to discern mistakenly the direction of inserting base 19 in the width center that is used for non-unlatching, first unlatching and second each the brake bars 15A to 15C that opens.
In the guide groove 17 of base 19, with the similar vertical return actuator 16 that slidably is provided with of sliding part 20 directions of motion.Return actuator 16 has a plurality of retainer springs 29 that are thin sheet spring form at predetermined longitudinal separation place, so that each brake bars 15 by button 14 pushings is remained on as shown in Figure 8 the pushing position.Simultaneously, and the irrelevant return actuators 16 of sliding part 20 push downwards by the decline spring 30 between the upper plate 19A that is inserted in actuator 16 upper ends and base 19 always.
Simultaneously, as shown in Figure 8, return actuator 16 is arranged in the inboard of the framework of sliding part 20, makes its lower end can abut the downside 20A of sliding part 20.Therefore, when sliding part 20 made progress (towards unclamping) motion, return actuator 16 also because of moving upward with its interlocking, made retainer spring 29 break away from brake bars 15 respectively whereby.
Shown in Fig. 7 and 8, on driving pinion 10, be provided with sector gear 32, it and pinion 10 engagements are so that the bolster 31 that is centered around on the direction of indoor and outdoor rotates.The releases pin 33 that is fixed on sector gear 32 left and right ends abuts the lower edge of sliding part 20.Therefore, under lock-out state, place restrictions on sliding part 20 and move upward, the releases pin 33 that abuts sliding part 20 lower edge prevents that sector gear 32 from rotating and prevents that also outdoor handle 7 from rotating.On the contrary, under opening, allow sliding part 20 to move upward, and allow bolster 31 rotations of releases pin 33, thereby also allow outdoor handle 7 to rotate around sector gear 32.
On sector gear 32 bolsters 31 of outside, the bearing 34 that is screwed on the outdoor handle 7 is arranged with spline fitted.Excircle around bearing 34 is equipped with unshowned helical spring.By means of this helical spring elastic force, outdoor handle 7 is got back to normal condition after rotation.
As shown in Figure 9, this embodiment has Arabic numerals " 1 " " 8 " and English character " C ", and they are engraved in retainer housing 16 surface and go up the left and right sides of associated button 14 and corresponding with button 14.In the middle of these numerals and character, the button 14 corresponding with numeral " 1 " to " 8 " is set at corresponding to non-unlatching brake bars 15A, first and opens the brake bars 15B and second any one of opening among the brake bars 15C.Simultaneously, the button 14 (reset button 14D) corresponding to symbol " C " that is in upper/lower positions is set at corresponding with the brake bars 15D that resets.
Shown in Fig. 1 to 4 and 6, each except the brake bars 15D that resets opened and non-unlatching brake bars 15A to 15C be formed with at a widthwise edges place be used for placing restrictions on the lock part 35 that sliding part projection 27 passes through and be used for allowing protruding 27 pass through unclamp groove 36.On the other hand, each brake bars 15A to 15C has three bump bonding 37A to 37C altogether at another widthwise edges place, and they have separately with predetermined space form the almost triangle top side face of level on retainer housing 6 fore-and-aft directions.By means of the triangular groove that between three bump bonding 37A to 37C, forms, on retainer housing 6 fore-and-aft directions, separate formation two bonding part 38A, 38B altogether, they will engage with bonding part, the top 29A of retainer spring 29.
In other words, each brake bars 15A to 15C of this embodiment has three bump bonding 37A to 37C and two bonding part 38A, 38B that are formed on brake bars 15A to the 15C width same side.Be defined as under the situation of the first bump bonding 37A, the second protruding 37B and the 3rd bump bonding 37C from rear side (downside from Fig. 6) order with respect to retainer housing 6 fore-and-aft directions at these three bump bonding 37A to 37C, so the first bonding part 38A at rear side forms between the first bump bonding 37A and the second bump bonding 37B, and forms between the second bump bonding 37B and the 3rd bump bonding 37C at the second bonding part 38B of front side.
Unlatching and non-unlatching brake bars 15A to 15C are contained in the brake bars patchhole 18 respectively and are on a kind of like this position, and the zone that promptly forms bump bonding 37A to 37C and bonding part 38A, 38B is towards return actuator 16.Simultaneously, form spring housing portion 39 (see figure 7)s at base 19 rear sides with the corresponding position of brake bars 15 (comprising the brake bars 15D that resets).Holding back-moving spring 40 in the holding portion 39, so that towards retainer housing 6 surfaces (towards the top of Fig. 1) pushing brake bars 15.
Therefore, when opening or non-unlatching brake bars 15A to 15D pushes arm 49L when depress at retainer housing 6 rear portions by what hereinafter will be referred to, bonding part 38A, 38B contact and are temporarily fixed at it with bonding part, the top 29A of retainer spring 29 and push the position.Yet when return actuator 16 was moved up by the brake bars 15D that resets, bonding part 38A, 38B and retainer spring 29 were disengaged, then brake bars 15A to 15D by back-moving spring 40 towards the pushing of the surface of retainer housing 6 and turn back to original position.
Simultaneously, in this embodiment, owing to form separatedly on the fore-and-aft direction of these two bonding part 38A, 38B in each brake bars 15A to 15C, two temporary fixed position stages (therefore, removing outside original not pushing position) are being set on the fore-and-aft direction that brake bars 15A to 15C depresses towards retainer housing 6 rear portions altogether.
Therefore, in this embodiment, detent mechanism 41 is made of following part: towards the back-moving spring 40 that does not originally push position pushing brake bars 15A to 15C, be formed on two bonding part 38A, the 38B of the brake bars 15A to 15C on the position spaced on the fore-and-aft direction of retainer housing 6, and retainer spring 29, this spring 29 is used for engaging any bonding part 38A, 38B so that temporary fixed brake bars 15A to 15C, whereby the temporary fixed position of brake bars 15A to 15C is arranged on two positions on retainer housing 6 fore-and-aft directions.
As shown in Figure 6, in the middle of brake bars 15A to 15C is opened in non-unlatching, first and second, non-unlatching brake bars 15A (Fig. 6 (a) and 6 (b)) has one and unclamps groove 36, and it is arranged in retainer housing 6 inside and is in a position near the rear portion with respect to its fore-and-aft direction (downside of Fig. 6).When brake bars 16A is in when not pushing the position, this unclamps groove 36 and overlaps with sliding part 20.
Simultaneously, first open that brake bars 15B (Fig. 6 (c) and 6 (d)) has that fore-and-aft direction with respect to retainer housing 6 almost is positioned at its center unclamp groove 36.When retainer spring 29 pinned in the first bonding part 38A, this unclamped groove 36 and overlaps with sliding part 29.In addition, second opens brake bars 15C (Fig. 6 (e) and 6 (f)) has the groove of unclamping 36, and it is positioned at close with on the position on the surface of retainer housing fore-and-aft direction.When retainer spring 29 pinned at the second bonding station 38B, this unclamped groove 36 and overlaps with sliding part 20.
Therefore, about non-unlatching brake bars 15A, when it even when being urged one time, its lock part 35 be positioned in the framework of sliding part 20 in case in recessed 26 the projection 27 of motion and joint sliding part 20, limit slippage part 20 moves upward whereby.Simultaneously, when non-unlatching brake bars 15A was in original non-pushing position, unclamping of it made sliding part 20 break away from its protruding 27 places and the contacting of brake bars 15A in the framework that groove 36 is positioned at sliding part 20.
Simultaneously, open brake bars 15B about first, when it did not push or pushes twice, its lock part 35 was positioned in the framework of sliding part 20 so that move in recessed 26, and engage the projection 27 of sliding part 20, limit slippage part 20 moves upward whereby.This is first when opening brake bars 15B and only being urged one time, and unclamping of it makes sliding part 20 break away from contact (the seeing Fig. 1 and 2) with brake bars 15B at its protruding 27 places in the framework that groove 36 is positioned at sliding part 20.
On the other hand, open brake bars 15C about second, when it did not push or push one time, its lock part 35 was positioned in the framework of sliding part 20 so that move in recessed 26, and engage the projection 27 of sliding part 20, whereby the (see figure 3) that moves upward of limit slippage part 20.Also have, when this second when opening brake bars 15C and pushing twice, unclamping of it makes sliding part 20 break away from the (see figure 4) that contacts with brake bars 15C at its protruding 27 places in the framework that groove 36 is positioned at sliding part 20.
Thereby, only preset the first and second unlatching brake bars 15B, when 15C pushes predetermined times, just allow sliding part 20 to move upward and open locking mechanism 13 whereby at this.Yet (for example push non-unlatching brake bars 15A or wrong press-started brake bars 15B, 15C many times) in other cases, sliding part 20 limits it by any one brake bars 15A to 15C lock part 35 and moves upward, and keeps the lock-out state of locking mechanism 13 whereby.Be noted that in Fig. 1 to 4 lock part 15 of brake bars 15 is all drawn hacures and is not with the hatched groove 36 that unclamps so that clearly be different from.
The brake bars 15D that resets is used for return actuator 16 moved upward so that will open and non-unlatching brake bars 15A to 15C turns back to original not pushing position.As shown in Figure 8, the brake bars 15D that resets has cam member 43, and cam member 43 has otch in its width end.Return actuator 16 has the inclined cam surface 44 that engages with cam member 43.
Therefore, when the brake bars 15D that resets by corresponding to the button 14 (reset button 14) of symbol " C " when pushing, return actuator 16 overcomes decline spring 30 by means of the joint between cam member 43 and the inclined cam surface 44 and moves upward.At this moment, because the retainer spring 29 that stretches out from return actuator 16 also moves upward, retainer spring 29 and brake bars 15A to 15C are disengaged.Turn back to original position so shift the brake bars 15A to 15C of temporary position onto by back-moving spring 40.
Shown in Fig. 1 to 4, there is the cross section to be the reinforced frame 46 of channel form in button 14 internal fixation.On reinforced frame 46 bottoms, fixedly push member 47, so that when button 14 pushing one time, sequentially pin by the first bump bonding 37A and the second bump bonding 37B of brake bars 15A to 15C.Thus, advance towards the rear portion successively in the temporary fixed position of brake bars 15A to 15C.
Push arm 49L, 49R about pushing that member 47 has that the fixed head 48 that is installed in stiffener 46 bottoms and a pair of sheet spring that stretches out from fixed head 48 two ends form downwards.Back-moving spring 42 at one end abuts the fixed head 48 that pushes member 47.Simultaneously, push arm 49L, 49R and have the step 50 that is formed on its vertical (vertical line among Fig. 1) center and extends along retainer housing 6 widths.
For being somebody's turn to do pushing member 49L, 49R about being positioned at, left arm 49L has towards brake bars 15 how many bendings so that can be by the top of bump bonding 37A, 37B pinning.And right arm 49R has towards leaving how many curved top portion of direction of brake bars 15, and arm 49L, 49R curve the right angle with respect to fixed head 48, so that arm 49L, 49R are parallel to each other being not applied under the nature of load.Be the width size that distance between two arm 49L, the 49R of parastate is slightly smaller than brake bars 15.
Shown in Fig. 1 to 5, indentation member 51 is stacked in the outside of base 19, and it is used for will pushing member 47 and places with the form of separating when button 14 is not urged.Indentation member 51 is formed with the short cylindrical projection 52 of stretching out towards retainer housing 6 surfaces at its width center.This projection 52 is installed in the other end of back-moving spring 42.
And arranged on left and right sides in the projection 52 of indentation member 51 forms a pair of pilot hole 53.Pilot hole 53 is inserted at the left and right top that pushes arm 49L, 49R respectively.Push arm 49L, 49R and be formed with triangular head 54 (see figure 5)s at its top, it has the function that prevents to deviate from from pilot hole 53.Respectively stretch out cam lobe 55 in left and right head 54 opposed facing planes, the edge that it engages pilot hole 53 pushes arm 49L, 49R so that broad ways is outwards expanded.
As shown in Figure 1, at the state that button 14 is not urged, cam lobe 55 is positioned pilot hole 53 inboards of indentation member 51, and the passage area W of brake bars 15 is left at the top that wherein pushes arm 49L, 49R.On the other hand, as shown in Figure 2, when button 14 pushing, cam lobe 55 is towards the trailing flank motion of retainer housing 6 and leave the pilot hole 53 of indentation member 51.At this moment, the top of left arm 49L enters the passage area W of brake bars 15 and is pinned by any bump bonding 37A, 37B.Meanwhile, also admission passage zone W and contact the widthwise edges of same brake bars 15 of the top of right arm 49R.
Under the situation of left arm 49L top by any first and second bump bonding 37A, 37B pinning, when further press push button 14, brake bars 15 is pushed towards retainer housing 6 rear portions by the top of left arm 49L, is relatively clamped by left and right arm 49L, 49R width at the same time.Bonding part, the top 29A of retainer spring 29 is engaged in bonding part 38A, the 38B that deeper locatees successively then, whereby brake bars 15 is positioned on the next temporary position.
In this manner, this embodiment is configured with intermediary agency 56, it constitutes by the first and second bump bonding 37A, the 37B that form in each brake bars 15A to 15C with for the left arm 49L that pushes member 49 that engages any protruding 37A, 37B, therefore, whenever button 14 pushing once, advance corresponding to the temporary fixed position of the brake bars 15A to 15C of button 14.
Simultaneously, in pairs about the pushing member 47 and have of this embodiment push arm 47L, 47R so that when releasing brake bars 15A to 15C, abut and clamp its width opposite edges.Therefore also provide this function: when width relatively clamps brake bars 15A to 15C, its rear portion towards retainer housing 6 is moved.
Using method and operation according to the push button locking device 1 of said structure are described now.
At first supposition is set in the unlatching number combination of using designated eight buttons 14 with " 1 " to " 8 " number and is opened number and for example be " 1,3,3,5,5,6 ".
In this case, brake bars 15A to 15C is contained in the brake bars patchhole 18, so that first open number " 1 " and " 6 " of brake bars 15B corresponding to button 14, second open brake bars 15C corresponding to the number " 3 " of button 14 and " 5 " but not unlatching brake bars 15A corresponding to other numbers " 2 ", " 4 ", " 7 " and " 8 " of button 14.
For the formula locking device 1 of releasing the button, can be according to the above-mentioned number of unblanking by number button for " 1 ", the button that be " 3 " and " 5 " by twice number respectively, and then the button 14 that to press number be " 6 ", turning cell handle 7 outward then.
So, the joint between the projection 27 of all brake bars 15A to 15C disengagement lock parts 35 and sliding part 20, thereby allow sliding part 20 to move upward.This just allows outdoor handle 7 to rotate.By means of swing handle 7, the latch of door 2 is drawn out of.Therefore no longer locking of door 2.
On the other hand, using the fault open number, promptly as pushing under the situation of button 14 lock part 35 bump bondings 27 of any brake bars 15A to 15C hereinafter in (1) to (3).This can limit slippage part 20 lock-out state of moving upward thereby keeping mustn't outdoor handle 7 rotating.
(1) pushes the button 14 that has number " 2 ", " 4 ", " 7 " and " 8 " corresponding to non-unlatching brake bars 15A.
(2) do not have or push for twice corresponding to first and open the reel number sign indicating number " 1 " of brake bars 15B or the button 14 of " 6 ".
(3) do not have or only once push corresponding to second and open the reel number sign indicating number " 3 " of brake bars 15C or the button 14 of " 5 ".
In addition, as user mistakenly during press-started number, pushing " C " button 14 (reset button 14D) thus start return actuator 16 by the brake bars 15D that resets so that all brake bars 15A to 15C are turned back to original uncompressed position.Then, can push correct unlatching number again.
In this way, according to the push button of this embodiment locking device 1, the temporary fixed position of brake bars 15A to 15C is arranged on two positions on retainer housing 6 fore-and-aft directions.In addition, on button 14, be provided with and push arm 49R, so that the temporary fixed position that button 14 of every pushing just makes brake bars advances successively towards the trailing flank of retainer housing 6.Yet, because brake bars 15 adopts second to open brake bars 15C as a part, so that unclamped in twice o'clock and the engaging of sliding part 20 advancing towards retainer housing 6 rear portions, at first to unclamp twice press-started operation of locking be feasible by pushing same button 14 twice methods.
Therefore, can under the situation that does not significantly increase button 14 and brake bars 15 quantity, increase the unlatching number combination greatly.So can under the situation that does not increase retainer housing 6 sizes, improve the safety of push button locking device 1 significantly.
Simultaneously, according to this current embodiment push button locking device 1, brake bars 15A to 15C by be provided with for each button 14 push member (pushing mechanism) 47 and be clipped in the middle in move towards retainer housing 6 rear portions.Therefore, even the center that pushes button 14 for example user during the pushing button, also can prevent that the thrust skew is delivered on the part of brake bars 15A to 15C with external position or on respect to the direction of retainer housing 6 some inclination of fore-and-aft direction.
Thereby, under the situation of pushing button 14, eliminated the interference in the brake bars 15A to 15C.Button 14 can push with relative lighter contact, thereby helps the open operation of button 14.
In addition, in the push button locking device 1 of this embodiment, when button 14 was not operated, the top of left arm 49L was placed on outside the passage area W of brake bars 15A to 15C by indentation member 51.Therefore, when brake bars 15A to 15C owing to return actuator 16 reset starting when turning back to original position, its bump bonding 37A, 37B can not pinned by the top of left arm 49L.So brake bars 15A to 15C can turn back to original not pushing position reliably.The kinetic energy that resetted is carried out reliably by return actuator 16.
Simultaneously, under this embodiment situation, when button 14 is not operated, constitute the left and right two arm 49L, the 49R that push member 47 and be extended to the state that is positioned outside brake bars 15A to the 15C passage area W by indentation member 51.The top of two arm 49L, 49R is by means of action button 14 admission passage zone W at first.So, owing to two arm 49L, two widthwise edges in 49R top and brake bars 15A to 15C contact the friction energy that causes and are suppressed at minimum degree.
Figure 11 illustration is according to the push button locking device 1 of second embodiment of the invention.This push button locking device 1 locking device as the individual mailbox of locking, this individual's mailbox constitutes aggregation type mailbox 58.
